| The aim of the present study is tomodificate sugar beet planter row spacing from 60 cm to 50 cm comparing with 40-60 cm row space (double furrows) using three different geometric shapes of opener with four levels of planting speed. The effect of study parameter were evaluated in terms of number of plants per feddan, seed scattering, root and sugar yield and water use efficiency. The modifications were conducted at workshop of Delta sugar Co., El-Hamool Factory while the field experiments were conducted at private Gad’s farm, Kafr El-Sheikh Governorate using Montbuanco variety during growing season of 2006/2007. The main results can be summarized as follow: -The minimum values of seed scattering were obtained with 40-60 cm row space comparing with other spaces at forward speed of 2.25 km/h and opener (A). -The highest values of number of plants per feddan and water use efficiency were 44900 plant/fed. and 0.0173 Mg/m3 with 40-60 cm row space at forward speed of 2.25 and 3.5 km/h, respectively with opener (A). flowed by 50 cm row space at the same conditions. While the lowest one was obtained with 60 cm row space and forward speed of 7.4 km/h when using opener (B). - Maximum values of sugar and root yield were obtained with 50 cm row space, machine speed of 3.5 km/h and opener (A). But the minimum values were obtained with 60 cm row space, machine speed of 7.4 km/h and opener (B). - Increasing the forward speed from 2.25 to 7.4 km/h tends to increase longitudinal, transverse scattering, root diameter and length by 144.44, 181.25, 11.32 and 15.45%, respectively at 50 cm row space and opener A, but the number of plants per fed., sugar and root yield, decreased by 24.71,22.98 and 26.09, %respectively at the same above conditions. | ||||
